Next you're going to need some kind of "movable alphabet" magnet is great. Blue is for vowels, so easier for kids to differentiate. Don't worry about the cards for now. Just focus on teaching the letters, them feeling the letters and associating sounds
Lovevery The Persister Play Kit This one is great for ages 4 and up, contains movable alphabet and flash cards to help your child learn to read CVC words
Cvc just means consonant vowel consonant - here they can move the slider as they sound out each letter slowly. Warning! This takes agesssss, months until they can blend the sounds. Don’t get discouraged!
Raised ABC flashcards help your kid learn the shape of each letter with integrating touch and sight. Play a game by having them guess the letter without their eyes closed!
